Transparent Calcium Zinc Stabilizer, related to CAS 557-05-1 (zinc stearate based composite system), is a lead-free heat stabilizer specially developed for flexible transparent PVC products. Formulated with optimized calcium-zinc soap and auxiliary stabilizer system, it delivers reliable thermal stability while fully retaining the high clarity and light transmittance of soft PVC. It avoids blooming and migration issues common in general CaZn stabilizers, making it ideal for clear flexible PVC fi

Product Detail

Product DetailsChemical IdentityProduct Name: Transparent Calcium Zinc Stabilizer for Flexible PVC CAS No.: 557-05-1 (core active component: zinc stearate, composite CaZn system) Chemical Type: Lead-free high-clarity calcium zinc soap heat stabilizer Physical Form: White fine powder / low-dust granular Core Feature: Lead-free high-transparency stabilizer for flexible PVC clear film, hose and toy

Key Performance & TDSThis transparent grade CaZn stabilizer provides balanced initial and long-term thermal stability during flexible PVC calendering, extrusion and injection molding. It effectively suppresses PVC thermal degradation and yellowing at processing temperature, while keeping the original light transmittance and low haze of transparent soft PVC. Its excellent compatibility with common plasticizers (DOP, DINP, DOTP) ensures no blooming, migration or surface fogging on finished transparent products. It maintains the softness, elasticity and mechanical properties of flexible PVC. Lead-free and cadmium-free composition complies with toy safety and food contact regulations. Fine particle size guarantees homogeneous dispersion during high-speed mixing, avoiding undissolved specks on clear film surface.
